To ALL WHOMIT MAY eoNoERN; Y

Be it known that I, W. W. SUTLIFF, of Town Line, in the count)l of Luzerne, and State of-Pennsylvania, declare that the following is a have invented a new and useful Improvement xn Gate-springyand I do' hereby full,` clear, and exact description thereo reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 represents a gate having my improved spring for closing attached. Figure 2 is atop view of the same.

Similar letters of reference indicate like parts. This invention relates to an improvement in a. spring for a gate or door, and consists in a dat curved metal spring, hinged at one end to the back of a gate, while the other end is free to catch in one of a series of notches in ablock fastened to the post or frame of a gate or door, which spring, by its pressure, keeps the gate closed when it is not forcibly pushed open to be entered or passed through.

A represents a gate hung on the post B. by hinges, in the ordinary way, and on the back of the gate a. lat curved spring, a, is hinged at one end, with the concave side outward, and the other end caught in a notch in a block. b, that is fastened to the post B, in s'uch manner that the spring is held while it is drawn up or contracted by the opening outward of the gate, to enable the spring to expand and close the gate again as soon as it is released by the person opening it. This operation of the spring is obvious, and the arrangement is simple, cheap, and effective for keeping gates and doors closed. The block b is provided with a. number of notches to set the end of the spring in, one or the other, according to the size of the gate, and the resisting power requiredl in the 'spring to make it act promptly. l

Having described my invention, I claim as nemend desire to secure by Letters Patent- The flat curved spring a, hinged to the' gate andv secured at one end in the notched block b, arranged and operatimlr as and fot` the purpose s ecitied. v
